Live 100NL - Flopped set on monotone flop

[Russ M.]

Live 100NL, 2/2 blinds

Hero has $100, villain covers

Hero is passive pre-flop, marginally aggressive post-flop but doesn't like to commit chips unless he's got a huge hand.

Hero limps 88 in EP, 6 more limp.

($14) Flop: Tc-8c-5c

Hero bets $10, villain immediately to hero's left raises to $30, all else fold.

What's Hero's plan for this hand? Villain is a typical live donk but hasn't shown anything incredibly stupid, however we've only played with villain for an hour or so.
